Description

本発明は、外壁表面に上下左右に並設された複数の外装材間の止水構造に関する。   The present invention relates to a water stop structure between a plurality of exterior materials arranged side by side on the outer wall surface in the vertical and horizontal directions.

近年、住宅の構築についてはその工業化が進み、例えば壁や床、屋根といった構成要素を予め工場にてパネル化しておき、施工現場でこれらのパネルを組み立てることにより住宅を構築するパネル工法が一部に採用されている（例えば、特許文献１参照）。
特許文献１のようなパネル工法では、隣接する外装材の側端部が、下サネと上サネとを係合させるサネ構造をなしているので、専用の取付金具を用いることによって、これら隣接する外装材を、外壁となる壁パネルに対して確実に取り付けできるようになっている。
特開２００１−０９８７３６号公報 In recent years, the industrialization of housing construction has progressed, and some panel methods have been constructed in which, for example, components such as walls, floors, and roofs are made into panels at the factory in advance and these panels are assembled at the construction site. (See, for example, Patent Document 1).
In the panel construction method as in Patent Document 1, the side end portions of the adjacent exterior materials have a structure that engages the lower and upper sane, so that these adjacent ones are used by using a dedicated mounting bracket. The exterior material can be securely attached to the wall panel serving as the outer wall.
JP 2001-098736 A

ところで、近年、上述のような外装材として、例えば軽量気泡コンクリートや、その他のコンクリート成形品等の建築用資材を用いたいという要望があった。このような建築用資材からなる外装材は、例えばポルトランドセメントと、石英及び溶融シリカを含む珪砂と、水とを混練してスラリーを製造し、このスラリーを格子状に組まれた鉄筋が配置された型枠に流し込み、さらに高温、高圧下のオートクレーブ内で蒸気養生させることにより製造されており、断熱性や防水性、防腐性、耐候性、デザイン性等に優れる。   By the way, in recent years, there has been a demand to use building materials such as lightweight cellular concrete and other concrete molded products as the exterior material as described above. The exterior material made of such building materials is, for example, a slurry prepared by kneading Portland cement, quartz sand containing quartz and fused silica, and water, and reinforcing bars arranged in a lattice form are disposed. It is manufactured by pouring into a mold and steam curing in an autoclave under high temperature and high pressure, and is excellent in heat insulation, waterproof, antiseptic, weather resistance, design and the like.

ところが、このような軽量気泡コンクリートや、その他のコンクリート成形品等からなる外装材は砂状のものを固めたものであるため、その側端部に、特許文献１の外装材のようなサネ構造を形成すると、細長く形成した部分や角部などが崩れ易くなってしまい、元の形状を維持できない場合があった。そして、このように外装材の側端部が崩れた場合は、外装材自体を交換しなければならなず手間であった。   However, since the exterior material made of such lightweight cellular concrete or other concrete molded product is a solid sandy one, the side structure has a sane structure like the exterior material of Patent Document 1. In some cases, the elongated portions, corners, and the like are liable to collapse, and the original shape may not be maintained. And when the side edge part of the exterior material collapsed in this way, the exterior material itself had to be replaced, which was troublesome.

そこで、このような手間を省くため、複数の外装材を隣り合うようにして外壁表面に取り付ける際は、例えばフラット面等のような単純化された端部同士を単に突き合わせるなどして、隣り合う外装材同士を並設していた。しかしながら、このように外装材の端部同士を突き合わせるだけでは、雨水等に対して十分な止水性を発揮することができない場合があった。   Therefore, in order to save such trouble, when attaching a plurality of exterior materials to the outer wall surface so as to be adjacent to each other, for example, simply abutting simplified ends such as flat surfaces, etc. Matching exterior materials were installed side by side. However, in some cases, sufficient water stoppage against rainwater or the like cannot be exhibited by merely abutting the end portions of the exterior material.

本発明の課題は、雨水等に対して十分な止水性を発揮することが可能な外装材間の止水構造を提供することを目的とする。   An object of the present invention is to provide a water stop structure between exterior materials capable of exhibiting sufficient water stoppage against rainwater or the like.
